Event Messages
Z This display units shows a four-digit event message for every
event. Trucks that only use one luminous display (e.g. LED) show
the event through a flashing code (see «Display System”).
Each event message is also stored in the master logbook. The
master logbook describes the event in more detail through the sub
index behind the event message (FEXX).
Event numbering display
F E XX S
F Function group; E Event group
XX Event number S Sub index
The first two characters “F, E” refer to the category. The middle
two digits “XX” refer to the event. From these two digits the range:
• 1 to 50 describes standard events (uniform basic events)
which can occur in any function group.
• 51 to 99 describes specific events.
The event is described in further detail through the last characters
“S” (single digit / multi-digit).
This process ensures that a unique number is assigned to each
event. Example:
0 Fault reset or
no fault
1 General fault / additional functions
Example:
Logic error, e.g. both directions selected simultaneously
2 Current
(input interface, device-internal, output interface)
3 Voltage
(input interface, device-internal, output interface)
4 Temperature
5 Hardware
Example: Output transformer short circuit, EEPROM not
responding, …
6 Software
(internal software, application software, data record /
parameters)
Example: EEPROM data error
7 Additional modules
8 CAN monitoring
9 External fault
Example: ISM

The code lock enables an operator or a group of operators to be assigned an individual user code. The user code is configured with a master code and is outlined in the following sections of this
chapter.
When you have entered the valid user code the truck will be operational. The truck will be able to perform travel, steering and hydraulic operations.
When you have entered the valid master code the truck will be switched on. Travel operations are inhibited. The truck will be able to perform steering and hydraulic operations. The code lock is
in programming mode. When you enter one of the following parameters the settings in the code lock can be changed.

The error may be triggered by the faulty speed sensor in connection with AS4814Plus controllers. Sensor wheel wobbles (elliptical) or the sensor- sensor wheel gap is too big. In this case the component is not faulty. A short circuit cannot be resolved by switching the truck off/on. |

CONTROLLER | Replace power part; Replace component.
Can occur in connection with error 70, in this case: check power supply behind the main contactor contact, in the event of an error the voltage will be much lower here than the rated operating voltage. Disconnect the positive supply from the components to target the error cause. The exception here is the F1 traction controller which must remain connected. One component overloads the testing voltage due to internal short circuit. The testing voltage arises by charging the internal capacitor batteries via a resistor to the level of the control voltage supply. |

Неполадки складской техники и их диагностика
Прогресс не стоит на месте, добавляя в устройство техники все новые агрегаты, поэтому конструкция специальных машин с каждым годом только усложняется. Однако, чем сложнее техника, тем сложнее ее обслуживание и диагностика.
К счастью, для облегчения работы и быстрого анализа поломок и внештатных ситуаций были придуманы специальные датчики, которые снабжают сервисменов информацией о конкретных точках поломки. Такая система уже давно работает в автомобильной промышленности и зарекомендовала себя с лучшей стороны.
Требование к погрузочной технике не является исключением, так как ее простой может обойтись бизнесу в круглую сумму. Важно, чтобы своевременная и быстрая диагностика, а также устранение неисправностей стали главными задачами.
Чтобы облегчить сервису по обслуживанию складской техники (ричтрак, вилочный погрузчик и электроштабелер) работу, были придуманы специальные коды ошибок и неполадок, которые указывают на точные проблемы, возникшие с техникой. Такая система не только ускоряет работу по ремонту, но и исключает человеческий фактор.
Какие коды существуют
Коды делятся на ошибки и неисправности. Их все можно с легкостью диагностировать и исправить в короткие сроки.
Самые часто встречающиеся неполадки и ошибки, которые можно диагностировать с помощью кодов
- Предупреждение о неправильной операции обучения
- Короткое замыкание верхних и нижних FET
- Короткое замыкание верхней стороны
- Короткое замыкание нижней стороны
- Повреждение провода фазы U
- Повреждение провода фазы V
- Повреждение провода фазы W
- Повышение температуры
- Температура не соответствует норме
- Короткое замыкание цепей нагрузки
- Мотор насоса (Повышение температуры)
- Мотор насоса (Температура не соответствует норме)
- Входной сигнал внешнего контролера выходит за пределы нормативного диапазона
- Неисправность датчика температуры контроллера погрузочно-разгрузочных операций
- Неисправность датчика температуры мотора насоса
Также спецзначки на панели приборов могут сигнализировать о необходимости технического обслуживания, замене технических жидкостей или о смене и подборе новой АКБ. Главное помнить, что, несмотря на кажущуюся простоту складской техники, ни в коем случае нельзя самому пытаться исправить ошибки. Чтобы избежать дорогостоящих расходов, всегда лучше обратиться в квалифицированную сервисную службу. Она своевременно и качественно починит все неполадки, и вам не придется ни о чем беспокоиться. Более того, в случае самостоятельного ремонта вы можете потерять гарантию на свою технику. Так как только после сервисного ремонта процент повторной поломки сведется к минимуму.
